"Smoke Dog, baby!"

There may be a 13 year age difference between us, but Miley Cyrus is bucking to become a future Ex Mrs. D.E.F.I. Her rep as a bit of a "bad girl", which had been slowly growing over the last couple of years, is beginning to snowball.

From MTV.com:

Last month, Miley Cyrus told MTV News about her plans for her 18th birthday, which she said would probably include "a fun party and then maybe ... a vacation with my family." On Friday (December 10), we finally saw footage of that party — or, at least a party — though Miley probably wishes we hadn't.

TMZ.com has posted a video clip of Cyrus smoking a bong — reportedly filled with salvia, a psychoactive (though, in her home state of California, technically legal) herb — and then collapsing in a fit of giggles while her friends egg her on ... and, somewhat inexplicably, Bush's "Come Down" blasts in the background.

"Having a little bit of a bad trip," Cyrus laughs in the video, moments after taking a hit. She then randomly switches topics, shouting (at something or someone off camera), "Is that Liam [Hemsworth]'s lookalike, or what the hell is that? Is that my boyfriend?"

She then spends roughly the next 90 seconds laughing uncontrollably while someone behind the camera asks her to "tell us your thoughts, girl, tell us what's on your mind!" and an unidentified man in the background totally houses a box of Frosted Flakes.

Honestly, reading about that party scene made me stop and question whether or not I was there.

Maybe it's my cynical side talking, but I'm really enjoying her descent from a bubblegum pop star persona into that of a dirty girl. All we need now is a Playboy pictorial around the time of her 19th birthday next year, and her transition to the Dark Side will be complete.

Miley—Call me, girl.
